Description
Technical field
The present invention is a kind of based on the rapid assay methods of microwave principle to the online moisture of gelatin type traditional Chinese medicine mixing process, belongs to Chinese medicine production technical field.
Background technology
Gelatin type traditional Chinese medicine is one of chief component of TCM Features, in China's application and recorded history has more than 2500 year, has good disease treatment and tonic and is worth.Gelatin type traditional Chinese medicine produce having of critical process glue, filter, carry foam, refine glue, plastic emitting and the glue etc. that dries in the air, wherein refining glue is one of most critical operation of its quality quality, in this operation, the quick detection of glue cream moisture is the important quantitative target evaluating refining glue degree, is also determine whether to enter unique evaluation index that the next one goes out glue process; Early stage, the working experience of old operative employee that relies on was predicted more, because of the impact of the many factors such as individual difference, input state, the plastic emitting moisture difference of certain batch of donkey-hide gelatin often can be caused larger.If plastic emitting moisture is too high, considerable influence can be had to follow-up glue time and the energy consumption of drying in the air, and finished product blob of viscose size heterogeneity can be caused, affect the exterior quality of product; If plastic emitting moisture is too low, can affects and follow-up cut glue yield rate.Therefore set up a kind of rapid assay methods being suitable for the online moisture of glue class Chinese medicine mixing process, to the energy-saving and emission-reduction promoted in glue class Quality Evaluation of Chinese Medicinal and production process, there is realistic meaning.
The assay method of current Chinese medicine moisture mainly contains oven drying method, the way of distillation, Karl_Fischer method (coulometry), supercritical ultrasonics technology, infrared absorption spectroscopy and high frequency damped method etc., wherein dry seasoning, the way of distillation and Karl_Fischer method, required time is longer, complicated operation, reagent consumption is large, all can not realize the fast monitored of online moisture.Supercritical ultrasonics technology and near-infrared absorption spectrum method refine the mensuration of glue degree and plastic emitting moisture to donkey-hide gelatin, owing to detecting, material color is dark, viscosity is large, easily adhere to detection probe, cause not having the signal of Signal aspects or display fainter in measurement, measurement result application condition is large; High frequency damped method is metallic object owing to refining glue tank, and have considerable influence to the decay that detector probe launches frequency electromagnetic waves to surrounding, the signal that inductor receives is fainter, and measurement result error is also larger.
Summary of the invention
For the limitation that glue class Chinese medicine plastic emitting water content detection prior art exists, the object of the present invention is to provide a kind of based on microwave technology and assay method, supplement other determination of moisture methods carry out quick determination of moisture limitation at high temperature, high viscosity, saturate non-newtonian fluid glue class Chinese medicine, establish the rapid assay methods of plastic emitting moisture, effectively can realize on-line quick detection to refining glue quality and plastic emitting moisture.
Object of the present invention is achieved through the following technical solutions:
A kind of online high-speed moisture determination method of gelatin type traditional Chinese medicine comprises the steps:
1) Zero calibration is carried out to microwave moisture meter, namely in the air of drying He in water, carry out Zero calibration respectively;
2) utilize microwave moisture meter to carry out the demarcation of moisture value coefficient, i.e. the tpAve value of the multiple sample of collecting test, then adopt oven drying method to measure the moisture value of this sample, the tpAve value of sample is associated with moisture value;
3) utilize the tpAve value of microwave moisture meter on-line testing testing sample, thus obtain the moisture value of testing sample online; The pass of the tpAve value of the moisture value measured and sample is: y=0.00000037724x
3-0.000487767505x
2+ 0.221312015231x-7.676490887099, y are moisture value, and x is the tpAve value of sample;
Wherein, described microwave moisture meter is the W300 on-line moisture determination instrument of German Ke Lei company;
Described glue class Chinese medicine is selected from donkey-hide gelatin, oxhide gelatin, deer horn glue or colla carapacis et plastri testudinis.
Preferably, described microwave moisture meter flange is fixed on concentration tank, and the probe of microwave moisture meter does not contact with the interior surface of concentration tank, and the degree of depth that sample covers probe is no less than 5cm.
Preferably, when described probe placement is in water, probe vertical does not have water height at more than 5cm.
The present invention utilizes and adopts the moisture of microwave moisture meter to gelatin type traditional Chinese medicine to measure, because the probe of microwave moisture meter can and tpAve value that saturate non-newtonian fluid detect material large to high temperature, viscosity measure, therefore with adopt the moisture value that measures of oven drying method to carry out associating to demarcate after, just can the moisture of the above-mentioned sample of on-line quick detection easily, and measuring accuracy is high.
Accompanying drawing explanation
Fig. 1 is the tpAve value of timing signal sample and the Trendline of moisture and multinomial coefficient figure.
Detailed description of the invention
Microwave method produces microwave by the microwave oscillator of device interior, and be transmitted to measured medium by waveguide, when microwave runs into hydrone in media as well, the energy of microwave and phase place can change.Instrument internal detection system can detect the change of atomic weak power and phase place, according to the energy surveyed and the mathematical relationship between phase place change and measured medium moisture, the rapid assay methods of moisture in glue class Chinese medicine mixing process can be set up by demarcating.
Further describe the present invention below in conjunction with specific embodiment, advantage and disadvantage of the present invention will be more clear along with description.But embodiment is only exemplary, does not form any restriction to scope of the present invention.It will be understood by those skilled in the art that and can modify to the details of technical solution of the present invention and form or replace down without departing from the spirit and scope of the present invention, but these amendments and replacement all fall within the scope of protection of the present invention.
